Since I'm incapable of making good comedy on my own in this thread have something I stole from not Wikiepdia

Now thin fruit flies like thunderstorms,
And thin farm boys like farm girls narrow;
And tax firm men like fat tax forms -
But time flies like an arrow!
.....
Like tossed bananas in the skies,
The thin fruit flies like common yarrow;
Then's the time to time the time flies -
Like the time flies like an arrow.
